PURPOSE: A control method of rapid lean mixed air by sudden acceleration during traveling after warming up and a system thereof are provided to prevent the lean state of mixed air by delaying the opening degree of the throttle valve with a control unit. CONSTITUTION: Sudden operation of an accelerator pedal(6) is checked by an accelerator position sensor(4), and warming-up traveling state is checked by a coolant temperature sensor(2). A control unit(10) decides the increase of an acceleration decision unit(12) according to a signal from the accelerator position sensor in operating the accelerator pedal during traveling, and a driving delay unit(14) stores the signal from the accelerator position sensor. Fuel is injected by outputting the increase signal, and a throttle valve(8) is opened by operating an actuator(16). The opening degree of the throttle valve is delayed finely by controlling the actuator with the control unit.
